The area of the circle would be 0.97
X = 17% of 350
17% = 17/100 = .17
Saying "of" in mathematics is like saying "multiplied by"
x = .17 * 350
x = 59.5
Now to solve this problem, all we have to remember is the
formula for calculating the linear speed given the radial speed, that is:
v = r w
where,
v = is the linear velocity or linear speed
r = is the radius of the circular disk = (1 / 2) diameter
= (1/ 2) (2.5 inches) = 1.25 inches
w = is the radial velocity (must be in rad per time) =
7200 rev per minute
Calculating for v:
v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)
v = 56,548.67 inches / minute
Converting to miles per hour:
v = 56,548.67 inches / minute (1 mile / 63360 inches) (60
min / hour)
<span>v = 53.55 mile / hour</span>

Example 1:
4x + 2 = 4x + 4....subtract 4x from both sides
4x - 4x + 2 = 4x - 4x + 4...simplify
2 = 4 (incorrect)
example 2 :
4x + 2 = 4x + 2...subtract 4x from both sides
4x - 4x + 2 = 4x - 4x + 2...simplify
2 = 2 (correct)
** if the variables cancel out....and u r left with an incorrect statement (like in example 1), then ur equations will have no solution
** if the variables cancel out...and u r left with a correct statement (like in example 2), then ur equations will have infinite solutions
